Cakephp 3.x update a record without form -

in users/index page list every user in users table doing following:

    <?php foreach ($users $user): ?>     <tr>         <td><?= h($user->name) ?></td>         <td><?= h($user->email) ?></td>         <td><?= h($user->phone_nr) ?></td>         <td><?= h($user->role)?></td>     </tr>     <?php endforeach; ?> 

user.role field enum type 2 choices: 'user' or 'admin'.

instead of listing user's role, need have dropdown able change right away. need like:

echo $this->form->input('role', ['type' => 'select','label' => 'role', 'options' => ['user' => 'user', 'admin' => 'admin']]); 

however, doesn't work outside of form , table not form.

any or guidance how solve appreciated.

edit

as requested, provide code snippet used save user data (if saved form):

public function add() {     $user = $this->users->newentity();     if ($this->request->is('post')) {         $user = $this->users->patchentity($user, $this->request->data);          if ($this->users->save($user)) {                          $this->flash->success(__('the user has been saved.'));             return $this->redirect(['action' => 'index']);         } else {             $this->flash->error(__('the user not saved. please, try again.'));         }     } } 

a simple approach 1 described below. makes use of no ajax, simple post request, means page reloaded when role changed.

modify view follows:

<?php foreach ($users $user): ?> <tr>     <td><?= h($user->name) ?></td>     <td><?= h($user->email) ?></td>     <td><?= h($user->phone_nr) ?></td>     <td><?= h($user->role)?></td>     <td>         <?= $this->form->postbutton('toggle role',             ['controller'=>'users','action'=>'toggle_role',$user->id,$user->role])?>     </td> </tr> <?php endforeach; ?> 

add action controller:

public function toggle_role($id,$existing_role){      $users = tableregistry::get('users');     $user = $users->get($id);     $user->role = ($existing_role == 'admin')?'user':'admin';     $users->save($user);     return $this->redirect($this->referer()); } 

_{note: code not tested, , lacks error handling}
